45. On Encephalic Irritation

Encephalic Tissue in Young Women

Background and Purpose: Recently, a rare syndrome that involves uniformly the brain, inner ear, and retina in previously healthy young women has been described. Brain biopsies and ophthalmologic examinations disclosed small infarcts as a pathoanatomical substrate of the disease. In previous reports, an autoimmune disorder or a coagulopathy have been suggested as possible etiologies. Case Descri...

Skin irritation and corrosion.

Small infarctions of cochlear, retinal and encephalic tissue (SICRET syndrome).

PURPOSE To report 3 new cases suggestive of SICRET syndrome. METHODS Case reports. Three patients underwent clinical, laboratory and neuroradiological examination for recurrent retinal branch artery occlusions, encephalopathy and/or hearing loss. RESULTS In all 3 patients the laboratory tests were unremarkable for infectious or systemic disease. All 3 cases showed retinal artery occlusions ...

Direct innervation of GnRH neurons by encephalic photoreceptors in birds.

In nonmammalian vertebrates, photic cues that regulate the timing of seasonal reproductive cyclicity are detected by nonretinal, nonpineal deep brain photoreceptors. It has long been assumed that the underlying mechanism involves the transmission of photic information from the photoreceptor to a circadian system, and thence to the reproductive axis. An alternative hypothesis is that there is di...
